Making and listening to music, and in particular playing (classical music on) the organ. I learned to play in my youth, but no longer had access to an organ once I left for university. As soon as I could, I did buy a synthesizer, and once I got a paid job, it grew until I had a complete in-the-box studio, but during Covid, nostalgia or some other bug got me, and I bought a (second-hand, digital) classical organ and started playing that. Discovering the literature is great, and playing it by myself is very fulfilling.
